M38 swede sights

I need a taller front sight blade for my '41 husky and am not sure what size to order or where from. The blade in it now is a -1 blade. I need to come down at 100 yrds about 9-10 inches. Which would be the closest to that? Thanks for the help guys.

I posted this in Gunsmithing too but thought I might have better luck here.

BsChoy: Try Brownell's for a front sight blank, maybe $5 and you'll have to file it down AT THE RANGE! Set a 5- or 100 yd target, shoot 2 from the bench, check target, file shoot, check, file, shoot....
